India to team up with Google for flood forecasting

NEW DELHI: India’s Water Resources, River Development and Ganga Rejuvenation Minister Nitin Gadkari has expressed hope that collaboration with Google will help in effective flood management in India.nnCentral Water Commission (CWC), India?s apex technical organization in the field of Water Resources, has entered into a Collaboration Agreement with Google.nnCWC would use state-of-the-art advances made by Google in the in the field of Artificial Intelligence, Machine Learning and geo spatial mapping for effective management of water resources particularly in the field of flood forecasting and dissemination of flood related information to the masses widely using the dissemination platforms developed by Google.nnThis initiative is likely to help crisis management agencies to deal extreme hydrological events in a better manner.nnUnder this Agreement, CWC and Google will share technical expertise in the fields of artificial intelligence, machine learning, geospatial mapping and analysis of hydrological observation data to collaborate on (i) improving flood prediction systems, which will help provide location-targeted, actionable flood warnings, (ii) high priority research project utilizing Google Earth Engine to help visualize and improve flood management and (iii) a cultural project to build online exhibitions on the Rivers of India .nnThe Ministry had earlier launched an ambitious programme ?National Hydrology Project? (NHP) during the year 2016-17. NHP is a World Bank assisted central sector scheme with pan India coverage. The objective of National Hydrology Project is to improve the extent, quality, and accessibility of water resources information, decision support system for floods and basin level resource assessment/planning and to strengthen the capacity of targeted water resources professionals and management institutions in India.nnThe initiative on flood forecasting is likely to meet the much awaited demand of the inhabitants of the flood prone areas for inundation warnings with sufficient lead time. Till 2016, CWC was disseminating flood levels with maximum lead time of one day. During the flood season of 2017, CWC resorted to rainfall based modelling and issued flood advisories on trial basis with 3 days lead time. Under collaborative arrangement, Google would use high resolution Digital Elevation Model and vast computational resources and its expertise in the field of Artificial Intelligence to generate flood inundation maps utilising the level forecast input provided by CWC.nnThe information in the form of likely extent and depth of inundation would be disseminated with a lead time of up to 3 days. For the flood season of 2018, inundation forecasting would be done on trial basis and the same would be up scaled in near future.nnThe collaborative arrangement is likely to result in saving of crore of rupees which otherwise would have to be spent by the government on acquiring high resolution DEM, high end computational resources and developing dissemination platforms widely used by the masses. This would enable the Government as well as disaster management organisations to identify well in advance the locations and population, which are at risk from floods and require warnings and information. This collaborative initiative is expected to be a milestone in flood management and in mitigating the flood losses.
